Abstract
The invention discloses a mold insert motion structure which comprises an upper mold, a lower mold, a mold core and a mold core ejection mechanism; the ejection mechanism comprises an ejection needle and an ejection needle plate; the lower end of the mold core is provided with an empty cavity; the empty cavity is internally provided with a slide block vertically sliding up and down; the side edge of a mold cavity of the mold core is provided with a plurality of inserts; the lower ends of the inserts are fixed on the slide block; the ejection needle plate is also provided with a plurality of ejection rods; a clearance is formed between the upper end of each ejection rod and the slide block; and the lower ends of the ejection rods are fixed in the ejection needle plate. The general inserts are combined with the ejection rods so as to form a novel insert motion mechanism, and a novel mode for solving air trapping is formed, and the appearance requirement of the product surface can be ensured, and the product reject ratio also can be lowered. In the prior art, the ejection needle or a flat ejector is used for exhausting air, compared with the existing ejection needle air exhaust structure, the mold insert motion structure can be used for enabling the inserts not to be difficult to damage; and the mold insert motion structure can exhaust the air fully, runs reliably, is low in cost, is convenient to form, and reduces the unhealthy phenomena in forming.
Description
Technical field
The present invention relates to a kind of mould, particularly a kind of mold insert motion structure of mould.
Background technology
Mold insert in mould as a dismountable iron block.Available extremely short time repairing mould after its effect mainly contains and facilitates mould dismounting and mould to damage, if use usual mould structure will cause the product fraction defective higher for some product, for example the bakelite series products is less, because the friction of the injection moulding of bakelite material is large, damage to dies cavity is comparatively fast used the fully exhaust of former thimble in normal situation, use less flat top fragile, exhaust is unstable and cost is higher.Thereby can't in time find the bad of product, the lost labor increases cost, and this type of mould is after inserting mold insert, and mold insert easily damages, and easily stops up mould, causes exhaust bad.
Summary of the invention
In order to overcome defects, the invention provides a kind ofly can increase die venting, reduces the mold insert motion structure of the mould that mold insert damages.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of mold insert motion structure of mould, comprise upper die and lower die, core rod and core pulling mechanism, described ejecting mechanism comprises thimble and ejector retainner plate, described core rod lower end is provided with a cavity, one slide block that vertically slides up and down is set in described cavity, the die cavity side of described core rod is provided with a plurality of mold inserts, the lower end of mold insert is fixed on slide block, also be provided with a plurality of push rods on described ejector retainner plate, be provided with the gap between the upper end of push rod and slide block, the low side of push rod is fixed in ejector retainner plate.
As a further improvement on the present invention, the upper end of described push rod and the gap between slide block are greater than the height of product
The invention has the beneficial effects as follows: the general mold insert of the present invention forms new mold insert motion with ejecting to combine, gone into the mode that a kind of new solution is stranded gas, can guarantee that product produces surperficial appearance requirement and also can reduce the fraction defective of product. existing technology generally uses thimble or flat jack-up to scavenging action, compare with existing thimble exhaust structure, this structure makes mold insert not fragile; And exhaust fully, reliable, cost is low, is convenient to moulding, reduces the bad phenomenon in moulding.
Description of drawings
Fig. 1 is structure die opening state schematic diagram of the present invention;
Fig. 2 is that structure die sinking product of the present invention ejects view;
Fig. 3 is that structure die sinking mold insert of the present invention ejects view.
In accompanying drawing, the mark of each parts is as follows: 1, patrix; 2, counterdie; 3, core rod; 4, thimble; 5, ejector retainner plate; 6, cavity; 7, slide block; 8, mold insert; 9, push rod.
The specific embodiment
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Fig. 1 has shown a kind of embodiment of the mold insert motion structure of a kind of mould of the present invention, comprise patrix 1, counterdie 2, core rod 3 and core pulling mechanism, described ejecting mechanism comprises thimble 4 and ejector retainner plate 5, described core rod 3 lower ends are provided with a cavity 6, the interior slide block 7 that vertically slides up and down that arranges of described cavity 6, the die cavity side of described core rod 3 is provided with a plurality of mold inserts 8, the lower end of mold insert 8 is fixed on slide block 7, also be provided with a plurality of push rods 9 on described ejector retainner plate 4, be provided with the gap between the upper end of push rod 9 and slide block 7, the low side of push rod 9 is fixed in ejector retainner plate 5, gap between the upper end of described push rod 9 and slide block 7 is greater than the height of product, during operation, after ejector retainner plate 5 moves up and by thimble 4, product is ejected core rod 3, push rod 9 just move to slide block 7 under, this moment, ejector retainner plate 5 continued to move up, push rod 9 withstands the slide block 7 end distance that moves up, mold insert 8 on slide block 7 moves simultaneously at this moment, the gas of script in die cavity is discharged rapidly, this kind structure mold insert does not participate in ejecting, the not fragile and well exhaust of mold insert.
Claims (2)
